Hola buen día.
Estoy estableciendo un tunel gre con ipsec.
Quiero agregar una ACL a la interfaz tunel, pero cuando agrego el crypto map a la interfaz tunnel se cae la vpn.
y si agrego el ACL a las interfaces fisicas no realizan el filtrado de las ip´s.
Como podría solucionar esto?
Agrego sh run de los routers

Hola,
no puedo ver ningun red local (LAN) en los routers. La ACL VPN-MTY es para definir el tráfico cifrado, normalmente el tráfico entre los dos redes locales. ¿Cuáles son los redes locales?

GRE tunnel need only IPSec profile why you config IPSec map?
